  1. 1. Hur påverkas elevers förståelse för multiplikation av areamodeller som representation? En designstudie i en grekisk grundskola med elever i Åk 2, där undervisningsprocessen fokuserar multiplikativt tänkande samt kommutativa lagen för multiplikation

    Master-uppsats, Göteborgs universitet/Institutionen för didaktik och pedagogisk profession

    Författare :Antelina Sema; [2024-03-04]
    Nyckelord :Multiplikativt tänkande; Areamodell för multiplikation; Kommutativa lagen; Proportionalitet;

    Sammanfattning : This design study explores the use of the area model as a representation of multiplication, providing opportunities for second school grade pupils to develop an understanding of multiplication and build multiplicative thinking. Furthermore, the study aims to give pupils the opportunity to discover the commutative law of multiplication with the help of the area model. LÄS MER

  3. 2. Problematic social media use and self-rated health among Swedish adolescents : Is the association moderated by perceived familial social support?

    Master-uppsats, Stockholms universitet/Institutionen för folkhälsovetenskap

    Författare :Åsa Ledel; [2023]
    Nyckelord :Adolescents; perceived familial social support; HBSC survey; SRH; Sweden; problematic social media use; ungdomar; upplevt föräldrastöd; HBSC; självuppskattad hälsa; Sverige; problematisk sociala medier användning;

    Sammanfattning : The purpose of this study was to explore the association between problematic social media use (PSMU) and self-rated health (SRH) among Swedish adolescent boys and girls, and additionally to examine whether perceived familial social support buffers against poor health in the same association. The study was based on the Health Behaviour in School-aged Children (HBSC) survey from 2017/2018. LÄS MER

  4. 3. School pressure and psychosomatic complaints among Swedish adolescents: does physical activity play a buffering role?

    Master-uppsats, Stockholms universitet/Institutionen för folkhälsovetenskap

    Författare :Alicia Birgersson; [2023]
    Nyckelord :School pressure; psychosomatic health complaints; physical activity; adolescents; moderation;

    Sammanfattning : Aim: The aim of the study was to explore the association between school pressure and psychosomatic health complaints and the potentially moderating effect of physical activity in a Swedish cohort of adolescents.Method: Cross-sectional data from the Swedish Health Behavior in School-aged Children (HBSC) survey of 2017/2018 was used, with participants aged 11-15 (n=3,745).

  5. 4. Constraining the Higgs width in Higgs production associated with a top quark pair

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Författare :Benjamin Dahlén; [2023]
    Nyckelord :Higgs; width; cross section; on-shell; off-shell; invariant mass; Standard model; upper bound; Physics and Astronomy;

    Sammanfattning : In this thesis we study the width of the Higgs boson in the process pp → t ̄t 4l at LO using MadGraph5_aMC@NLO to generate the events. The contributions including the Higgs signal, continuum background and interference were considered in order to calculate the expected number of events in a broad range of four-lepton invariant masses.

    Sammanfattning : Almost every company around the world were aected by the COVID-19 crisis and the government measures that were taken to slow the spread of the virus. The impact the crisis had on the economy caused the appearance of anomalies in the data collected by companies : such as abnormal trend, seasonality etc. LÄS MER
